Title: deal with upload errors

deal with 200 responses that contain error messages on a failed upload
add generic error handler for displaying these errors with cancel button
hide all existing popups when showing a page (this deals with the case where
the uploading status message popup is open and then loads the error popup)

when cancelling the error message the previous upload screen is shown hence
the update of upload message
see #21 for cancelling an upload
